Consider a pipe of length 80.0 cm open at both ends. what is the lowest frequency f of the sound wave produced when you blow int
SOVA2 [1]
To answer the problem we would be using the formula:v=λ*f
where v=343 m/s
length of standing wave
λ=2*L=1.6m (since both of the ends are open),
L=80.0cm =0.8m; but we are going to rearrange it.
Therefore fundamental frequency is:
f=v/λ
= 343/(2*0.8)
=214.375 Hz

Tyler’s brother works in a shoe store.
AnnyKZ [126]

Answer:

Step-by-step explanation:

A) To figure this out, convert 2.5% into a decimal, which is 0.025. Then, multiply the amount he sold by his commission percent. So $9000 * 0.025 =$225

B) The formula for percent change (or in this case percent markup) is (new value - old value)/old value *100%. So, (80-50)/50*100% = 30/50*100%=60%.

C) First, calculate the amount his hourly rate will increase by. So, multiply 12 by 5%, which is $12*0.05=$0.60. Then, add this amount to his current hourly rate. So he now makes $12.60.

The temperature in degrees Celsius can be determined using the expression 5 9 (F – 32) where F is the temperature in degrees Fah
Norma-Jean [14]

Answer:

The temperature on Celsius scale for 86 ºF is 30 ºC.

Step-by-step explanation:

Both degrees Celsius and Fahrenheit are relative scales of temperature. The relationship between degrees Fahrenheit and degrees Celsius is summarized by the equation below:

T_{C} = \frac{5}{9}\cdot (T_{F}-32) (1)

Where:

T_{F} - Temperature, measured in degrees Fahrenheit.

T_{C} - Temperature, measured in degrees Celsius.

If we know that T_{F} = 86\,^{\circ}F, then its equivalent temperature on Celsius scale is:

T_{C} = \frac{5}{9}\cdot (86-32)

T_{C} = 30\,^{\circ}C

The temperature on Celsius scale for 86 ºF is 30 ºC.
